Steven Tyler's gift to his feet? Christmas in rehab!

To hear Steven Tyler's doctor tell it, the Aerosmith frontman's addiction to painkillers has less to do with hard living than with, well . . . old age. Tyler's feet and knees are killing him from years of performance wear-and-tear: the chronic pain is evidently so had that he'll need surgery before getting back in the saddle again.

Observation: You don't hear Keith Richards blaming the drugs on geriatrics, do you?

Tyler released a statement today that he's entering rehab to get off the painkillers. Presumably, this will also be a chance for his accountant to knock some sense into him, and to persuade him not to do any more of that breaking-up-Aerosmith nonsense.
